This invention reiatesio'eard-disp1ay de vices and has for-itsobject theprovision of a device of' the character `specified having novel meanswhereby a number of cards may be exposed in rapid sequence so that thematter on the several cards may be viewed'. p

A furtherl aim of the inventionis to pro- A videnovel means wherebythecards are support-ed so that the Vcontinued .exp'osureof the same willnot weaken' orfcrack the cards or the means of securing the same to theflexible strip, thesaid 'flexible strip Vconstituting an operatingA andsupporting means for the cards. n Y A further object is to provide adisplay device oi.v the ycharacter specified which is of highlysimplified construction, i sirnple to opera-te and cheapto manufacture.`

n `.Infthe accompanying drawings forming a part ofA this applicationandiny which like numerals are employed to designate like partsthroughout the Same,

vFigure 1 is an'elevation of the improved display device, the cardsbeing concealed.

Figure 2 is also an elevation of the improved display device, certain ofthe cards being removed from the casing and one of the cards being inupright position so that the matter thereon may be readily seen.

Figure 3 is a vertical transverse sectional view through the improveddisplay device.

Figure 4 is'an elevation of aslightly'modified form of the invention.

Figure 5 is a fragmentary perspective illustrating the connecting meansfor the cards.

Fi re 6 is a detail elevation' illustrating the modified form of theinvention.

Figure 7 is a side elevation illustrating a modified form of theinvention.

In the drawing wherein for the purpose of illustration is shown severalpreferred .embodiments of the invention the numeral 10 vdesignates acasing which is of elongated formed of cardboard or other suitablematerial and is reinforced by means of backing the flexible strip v13.necting strips l2() have their ends secured to strips 11 secured behindthe front wall of the casing by means of fiaps 12 or other suitablefastening devices. j

As illustrated in vFigurev 3 a continuous flexible strip. 13 of tape orthe like is eX- tended about the vfront wally of `the casing andsupports a plurality of cards 14 each one of which isprovided with apicture slightly different from the pictures on the adjacent cards, sothat as the cards are'rapidly moved' `and exposed to view, the objectsapplied yto j the severalk cards will appear to move.

The cards 14 are provided with transverse slots IG'at'points spacedfromtheir lower ends and the said slots receive the continuous strip 13. Theseveralfcardsy have their porltions adj acentthe slots 1 6 glued orotherwise f secured to the` continuous strip'13 "so that one card isnotpermitted to moveon the strip' and thereby get out of place.A Asillustrated in Figure 5 the several cards 14 are joined by avpair ofparallelflexible connecting strips 2O arrangedo'n opposite sides of' Ofcourse theconthe'endV cards and the intermediate portions of theconnecting strips are preferably glued to the backs of the severalcards. The connecting strips 2O ofwhich there are two hold theseveralcards in position with relation to ythe other cards so" that the samemay be rapidly exposed vto view. However, the strips 2O do not detractfrom the appearance of the device as the several strips are secured tothe backs of the cards.

In operation the several cards may be withdrawn fromv the casing bypulling down on a finger piece 23 ,formed on member 13.

The severalfcards may be provided withV pictures as illustrated inFigure 2 or with data as illustrated in Figure 4. In Figure 4 the frontwall oi the casing may also be provided with data for use in an ofliceand the improved display device in that case may be suspended from thewall in any 'suitable manner or supported on the desk;

When all the cards are concealed within.

the casing the finger piece 23 isgrasped and drawn downwardly so thatthe cards will be quickly exposed in rapid succession. This causes therapid change of view so that the objects in the picture appear' to move.When it is desired to return the cards to within the casing it ismerelyneces'sary to pull upwardly on the finger piece 23 so that thecontinuous strip 13 will be operated. By

reason of the means employed for connecting the cards to the strip 13continued use of the device will not break the connection between thecards and the strip.

in the modified form of the invention illustrated in Figure 6 theseveral cards 30 are provided with transverse slots 31 for the receptionoitl a pair of spaced parallel strips A connecting strip 33 ot' anysuitable material is glued or otherwise secured to the backs of thecards and forms a ineans for supporting the same.

in the forni oi? the invention ill strated in Fig. 7 the endless strip4() is trained about a roller or drinn il and about a smaller roller Ll2rotatably carried by the Vears 453 oi a iraine LM. e The traine la isalso provided with a pair of rearwardly projecting brackets 45 whichrotatably support the drinn fil. The shaft +15 oit th e drinn inay beprovided With a crank fl? by ineans of which the drum niay bc rotatedfor operating the several cards i8 carried by the endless strip.

iiilith :reference to the foregoing description taken in connection Withthe accom- )an Yino` drawings it will. be a) )arent that l es a theiniprored display device capable cfa variety of mechanical expressionsand it is also understood that the several 'forms of the inventionherewith shown and descriliied are to be talien as preferred examples ofthe saine and that such ininor changes in the arrangement andconstruction of parts may be nitide as will remain within the spirit otthe invention and the scope oi' what is ilain'ied.

The inventive idea involved in this application n'iay be applied tovmotion pictures, card indexes, books, calendars, lists of varions kinds,calculation tables, valentines,

etc., and the device may be made from paper, metal, Celluloid, Wood orother desired Inaterial.

Having thus described the invention, what is claimed is l. A device oi'the character specified coinprising an elongated casing having its endsopen, a continuous strip passed about the front Wall oi' said casing andhaving a lin ger piece, by means of which the strip may be operated, anda plurality of display cards having their rear portions formed withslots receiving` said endless strip.

Q. A device oit-the character specified coinm prising an elongatedcasing having its ends open, a continuous strip passed about the frontWall of said casing and having a iinger piece, by n-ieans of whichthe'stri) may be operated, a plurality of display car i s hav ing theirrear portions formed with slots receiving said endless strip, andconnecting strips secured'to the rear sides of said cards on oppositesides of said endless strip.

3. A device ot the character specified coniprising an elongated casinghaving its ends open, a continuous strip passed about the` front Wall ofsaid casing and having a linger piece, by means of which the strip maybe operated, a plurality of display cards having their rear portionsiornied with slots receiving said endless strip, connecting stripssecured to the rear sides of said cards on ppositcsides ot said endlessstrip,` and a reinforcing member secured to the front Wall of saidcasing and surrounded by said endless strip, said cards being adapted tobe received within said casing.
